DATAFILE: HONO2_Brown(1999)_298K_213.86nm.txt
NAME: nitric acid
FORMULA: HONO2
AUTHOR(YEAR): Brown(1999)
T: 298K
λ: 213.86nm
BIBLIOGRAPHY: S.S. Brown, S.S., R.K. Talukdar, and A.R. Ravishankara, "Reconsideration of the rate constant for the reaction of hydroxyl radicals with nitric acid", J. Phys. Chem. A 103, 3031-3037 (1999); DOI: 10.1021/jp984721k
COMMENTS: Measurement of HONO2 concentrations by absorbance of the 213.86 nm line from a Zn lamp in a room temperature absorption cell

The value (4.52 ± 0.19) × 10-19 cm2 molecule-1 was interpolated from the room temperature measurements of

J.B. Burkholder, R. Talukdar, A.R. Ravishankara, and S. Solomon, Temperature dependence of the HNO3 UV absorption cross sections, J. Geophys. Res. 98(D12), 22937-22948 (1993); DOI: 10.1029/93JD02178,

where the 4.2% uncertainty arises from the uncertainties in the absorbance measurements of Brown et al.
